Well, there is $cobalt(II) oxide$ $"cobalt(II) oxide"$ , $C o O$ $CoO$ ..... $cobaltous oxide$ $"cobaltous oxide"$

Explanation:

And $cobalt(III) oxide$ $"cobalt(III) oxide"$ , $C o_{2} O_{3}$ $Co_2O_3$ ..... $cobaltic oxide$ $"cobaltic oxide"$ .

And a mixed oxidation state oxide exists, $C o_{3} O_{4}$ $Co_3O_4$ (note that I simply added the given formulae together, $cobalt(II,III) oxide$ $"cobalt(II,III) oxide"$ ).
